I don't know about the TE position, safety spots, and ILB positions being set. They may be set for now but they are upgradeable, which IMO relates to not being "set".
TE: Bruener is good, but he's getting older, and if Joppru ever recovers then we could be set. Note the if in relation to Joppru.
Safety: A young gun for depth and future replacement is needed. I love Eric Brown in run support, but as we saw Sunday, his coverage skills leaves a little to be desired. He will knock the snot out of you, and I absolutely love that about him.
ILB: Foreman is good, but he is upgradeable.
I'm a hell bent 100% Texan till I die...
